This Christmas, the unforgettable pupils of St. Bernadette's are heading to Wales to compete in the National choir contest; 'A song for Christmas'. New supply teacher Mr Peterson (David Tennant) has the unenviable task of trying to curb the hysterical enthusiasm of the kids - not to mention Mr Poppy (Marc Wootton) - but reluctantly finds himself getting swept along! St. Bernadette's hit the road (without parental permission!) in an amphibious tour bus crammed to the heavens with Angels, Shepherds and an unaccompanied baby! Hot on their heels are their arch rivals Oakmoor and this year's new challengers St Cuthbert's College, led by Mr Peterson's golden boy identical twin brother. Over land and water, charting mountains and caves and with a donkey in tow, the gang learn to conquer their fears, work as a team and trust their new teacher. However, time is running out and the singing competition does not accept latecomers... Under the stars on one magical night the sparkle and shine of Christmas once again comes to life in NATIVITY 2: DANGER IN THE MANGER!
